It is posible to find love or think "only sex"? Ive never had a girlfriend

Well Ive never had a girlfriend, the last one that i liked a lot, was because she looked beautiful inside and out, she was smart(she beat me in chess xD), funny and and i liked her a lot, well she was one of those girls that are extremely beautiful, but she was not an ass, she even dressed some like punk, i mean she looked very especial. Well i meet her, talked to her, and well she is like 1-2 year older than me, she already goes to university, so all that in 2 days because, the reparation of computer curse in which i met her was going to end the next day my friend introduced her to me, so i asked her number and tell her about going out, and she say yes(Wednesday) but the Friday when i talked to her, she started giving excuses and next she tell me that the Saturday was going to go out with her boyfriend(i didn't know she had boyfriend), so i tell her "ok i understand, well easy, take care ok =)" and well that's how my story ended. Actually she was the first girl i ask out on a date. But i have some serious doubts, i will like to have a girlfriend which i can love, be faithful to each other, and have our fun =) but when i see around, i only see unfaithfulness, no love, crying or girls that only like the "bad guy" (I don't think is the bad guy i think is confidence) that only wants sex. Well so i will like to know if am only a Quixote and i should start thinking in "only sex" (that make me kinda sad) or is there any chance that i find a girl that i like INSIDE and OUT a lot and have love, faithfulness, and fun.
